I’m using Internet Explorer 8 and the background doesn’t load.
Go to Extensions > Template Manager > vg_bismuth – xxx.
In the params, Slideshow. Choose an image for the Image 15 as the final one (no matter that Image 4, Image 5, Image 6 or more are empty). – See the attachment image.
Save and that’s it!
Remember: Always loads the Image 15 as your last Slide
